Five Things You've Never Learned About Cut Car Key > 자유게시판

Car Key Cutting Explained

Cutting keys for cars is more than just bending a piece of metal. It is a complicated process that ensures security, functionality and durability of keys.

It is not unusual to lose your car keys or have it break off in the lock. You will need a replacement car key to ensure you can drive your vehicle at all times.

Transponder Keys

If your car was constructed within the past 20 years, it is likely that it has transponder chips. These chips are small microchips in the handle of your key that send signals to the car's onboard computer when you are using it. The onboard computer is able to verify the digital serial number of the chip prior to giving the car permission to begin. This prevents car theft as thieves would have to know your unique serial number in order to have a chance at hijacking it.

The microchip in your car keys transmits an unintentional radio signal to the car's receiver. The radio signal activates microchip, and it then sends a code to the car's onboard computer. The car will be able to recognize this code and only allow it to start only if it is the correct one. This will stop the use of "hot wiring" and other methods of taking cars.

Locksmiths who offer these services can create car keys with chips. Some automotive retailers such as AutoZone sell them. Those stores carry a huge selection of keys and can assist you in choosing the appropriate one for your vehicle. They can also help you programme the chip into your vehicle, which is essential to make it work.

You can also purchase laser cut keys that are more secure than traditional flat keys. These keys feature a lock cylinder that is more difficult to pick, and they are only duplicated using expensive laser key cutting equipment or special software. This type of technology is typically found in luxury vehicles, but it is now available in a wide range of low-cost cars too.

Another type of key for cars that is difficult to duplicate is the VATS (vehicle anti-theft system) key. The keys have a resistor that is black on the blade of the key. It can be programmed with one of fifteen possible values to stop it from starting a vehicle it's not designed to. These keys are more expensive to buy and require a special key programming device that can only be found at some locksmiths.

VATS Keys

Before the advent of transponder keys and cars equipped with computer chips that control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an embedded resistor to verify that the correct key was used to start the car. The black VATS Pellet that is located in the middle of the VATS Key is not an electronic chip that is like those present on modern keys. It is merely carbon or a block that is sized to have an electrical resistance value.

GM used 15 different resistance values for the VATS pellets. They connected them to the blade of the key, so that when the key is turned on the ignition a coded signal will be sent to the module. If the signal matches the resistance value of the transistor in the VATS pellet the relay in the starter circuit is activated and the engine starts to run. This doesn't make a car theft proof however it will delay the theft by at minimum 15 to 20 minutes.

After a lot of usage the VATS module may begin to wear out. Each time the key is inserted into the ignition, it moves two tiny wires within the ignition, and with time, the wires could start to break. Once enough wires break, the signal to the module gets not received and it will not start the car.

You can solve this problem at home by decoding your VATS code. It's not hard to determine the resistance of a key with a multimeter. You can determine the resistance value by putting one of the leads on the prongs of metal on both sides of your key.

This can also be a good method to test a new key to determine whether it will work in your car. Remove the key from the ignition first before you test it. In the event that it is not removed, the key may have an incorrect VATS and will not function in your vehicle.

Smart Key Fobs for Keys

Key fobs of today can do more than unlock or start a car. They also function as an alarm system and a burglar deterrent, with a lot of them incorporating advanced features that the owners might not even be aware of. They can remotely lock and unlock your doors, emit chirping sounds to help you locate your car keys cut by code in a parking lot, or even allow you to summon your vehicle by pressing the button on your smartphone. This is a lot more functionality than you can get from a standard keychain remote. However, all that additional features also means that smart key fobs can be more expensive to replace than standard keychain remotes, and they usually need to be programmed by the dealer.

In fact, some dealers cost upwards of $100 to replace one smart key fob. That's a lot to pay for something that is often time in purses and pockets where it is easily damaged, dropped or exposed to extreme moisture and temperatures. Certain automakers have devised methods to protect smart keyfobs from common electronic attacks, such as relay attacks. These are usually employed in conjunction with a remote-start hack that allows thieves to access the settings of your vehicle by sending an untrue signal from a nearby transmitter.

One method of protecting the key fob's RFID is to put it in an aluminum case or a dedicated RFID blocking case that prevents the transmission of these signals. However, the necessity of removing the key fob from a case that is protected each time you need to use it undermines the convenience of the technology.

Fortunately, a few of the latest car insurance policies and auto club memberships and extended warranty coverages will pay for the cost of replacing a fob or pay for the loss of a fob. You can also save money on dealer fees and have your fob cut at a hardware store or locksmith who offers key fob cloning.

The only disadvantage of using traditional keys is that it must be physically placed into the ignition to start the vehicle.
